石油钻头三角聚晶磨损试验方法的研究

METHOD FOR WEAR TEST OF BIT TRIANQULAR POLYCRYSTALS

对人造金刚石三角聚晶在模拟实际工况的条件下，进行了耐磨性试验研究．主要从三角聚晶的磨损机理和微观结构研究了三角聚晶的耐磨性，从而全面评价聚晶的质量，寻求测定耐磨性的新方法，为聚晶的实际应用提供了可靠的依据．

Wearability of aritifical diamond triangular polycrystals was investigated under model-ing operating conditions.The wear test method of bit triangular polycrystals and wearability were ana-lyzed with force-summing and microscopic behavior.The result of the teeth is useful for evaluation ofpolycrystals quality.
